This Colorado road cycling guide describes 141 road cycling routes with maps and elevation profiles and total gain and loss. Road Biking Colorado splits the state into different regions from which you can select your rides. I’m familiar with of the routes listed in the “North Front Range” section of the book, which describes most routes on a single page, though the magnificent Trail Ridge Road in Rocky Mountain National Park merits four pages. This book would be a decent gift for your Valentines Day honey if you cycle in Colorado.
